Common questions
What does a typical Mindrift task involve?
Read a scenario, write a short prompt for the AI (around 100 words), evaluate two AI responses to it, fact-check the outputs, then write a brief explanation (around 50 words) on which response is better against the project rubric. The focus is clarity, safety, and rule-following, not creative writing.
Who is Mindrift good for?

Short, hands-on tasks such as recording videos, sorting images, rating AI answers or checking data. Most take 5 to 60 minutes each.
Can I choose my own hours?
Usually, yes. You log in when you want, pick up a task, finish it and submit it, with no meetings. Other people work from the same pool of tasks, so some days there may be no work until more is added.
